This is a constant struggle in design, even (especially) when targeting highly technical audiences. We frequently conflate the familiar with the simple or user-friendly. People will shout "how intuitive!" when a designer repeats an interface that's currently familiar in a context that forgets why the original interface was helpful. So we get a few nice touch gestures: scroll, zoom, etc. We then expand adding more until learning all your gestures (on that particular os for that particular hardware) is more complex than ASL.
